BTEX, the selected gasoline oxygenates/additives <br /> ' and TPH-G were not detected at or above the laboratory reported detection limits in the groundwater <br /> sample collected from MWl. Toluene, ethyl benzene, and TPH-G were not detected at or above the <br /> laboratory reported detection limits in the groundwater sample collected from MW2. Benzene, xylene, <br /> MTBE, tertiary butanol, and TAME were detected in the groundwater sample collected from MW2 (0.4, <br /> ' 1.5, 550, 72 and 3.6 µg/1, respectively). BTEX and TPH-G were not detected at or above the laboratory <br /> reported detection limit in the groundwater sample collected from MW3. MTBE was detected in the <br /> groundwater sample collected from MW3 (7.9 µg/1). BTEX, MTBE and TPH-G were detected in the <br /> ' groundwater sample collected from MW4 (1.6 gg/I, 0.4 µg/l, 2.0 µg/1, 22 µg/1, 14 µg/1, and 0.8 mg/l, <br /> respectively).
